Some control problems for near space hypersonic vehicles

The characteristics of near space hypersonic vehicles have brought about new difficulty in modeling and control. Firstly, this paper analyzes some characteristics of hypersonic vehicles, and then puts forward the unified model in the large envelope flight. Secondly, an overview of current control studies on the cruising phase and the reentry phase is presented, where the problems of flexibility, non-minimum phase, integrated design of reentry guidance and control are emphasized. Finally, with the development of hypersonic vehicles, the interception issue of hypersonic targets is discussed, which provides the potentiality for future research.
